First of all, you need to understand that not all hydrangeas produce a blue flower. Some of the plants may produce a white or cream color flower, while others may be able to produce the blue hydrangea that you implore about.

The hydrangeas that normally produce various bloom colors that range from different shades of pinks to blues to even shades of purple belong to a particular species of hydrangea plants known as mopheads or lace caps.

These particular species of plant have the ability to change the color of the flowers that they bloomed based off of the pH level of their soil. When the flowers are grown in an alkaline based soil the flowers will come out in a pink color sequence, however when the flowers are grown in a more acidic soil they will sprout out blue flowers instead.

Because the overall soil chemistry determines if you will be able to obtain a blue hydrangea or not the variety of names that these plants bare really do not make that much of a difference. For instance the clever names that they bare such as Nikko Blue or Forever Pink has a chance of blooming up wither pink or blue depending on the soil that the plants are planted in.

One thing you need to remember when buying hydrangea plants is you may not always get the particular bloom color that you are seeking. The bloom color is not a basis of the plant, but is based along the lines of the soil that you decide to put the plant into.

In order to encourage the growth of the blue hydrangea plant you need to ensure that you grow the plants in a soil that has a pH level that ranges from 5.2-5.5. If your soil consists of more alkaline then the designated pH level to be able to sustain the blue blooms you can try to lower the level by adding 2 TBSP to the area where you plan to bloom the plant.

Soil pH can also be lowered by simply applying mulch to the ground that is full of acid or by inserting pine needles or pine bark to the soil that you wish to plant in. However, if your alkaline level is simply too high and you cannot lower the pH of the soil then your chances of growing blue hydrangeas is pretty much useless.

Alkaline soil tends to lock up the amount of aluminum found in the soil that the plant needs in order to bloom out the blue flowers that you desire. You can still do certain things that will help the blue hydrangeas bloom; however the soil is the deciding factor in the ordeal of the flowers being the specified color that you want.
